[0002] Sludge treatment is a crucial step in reducing, stabilizing, and rendering harmless the sludge residue generated during wastewater treatment. The higher the level of wastewater treatment, the greater the amount of sludge that needs to be treated. Common sludge treatment methods include: Compression and dewatering: Removing water from the sludge through mechanical compression and physicochemical methods to reduce its volume, facilitating subsequent transportation and disposal. Incineration: Using high-temperature combustion technology to convert sludge into ash, achieving harmless treatment. Composting: Mixing sludge with other organic matter and composting to produce organic fertilizer for agricultural or landscaping purposes. Biological treatment: Using microorganisms to degrade and decompose sludge, converting it into usable energy sources or useful compounds such as biogas and methane. In practical applications, it is necessary to consider local policies and regulations and specific circumstances, taking into account economic, environmental, and safety factors to select an appropriate method. Simultaneously, monitoring and management of the entire sludge treatment process should be strengthened to effectively prevent the risk of secondary pollution.
[0003] However, existing equipment cannot quickly separate sludge from water, requiring a significant amount of time for sedimentation and filtration, resulting in low efficiency. Furthermore, the presence of large clumps in the sludge further reduces efficiency. Summary of the Invention

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1
[0030] Reference Figures 1-8 This is the first embodiment of the present invention, which provides a sludge-sewage separation device.
[0031] Specifically, the screening component 100 includes a conical screen 101, a support plate 101a is provided on the top of the conical screen 101, a protrusion 101b is provided on the outer side of the support plate 101a, and a spring 101c is fixedly provided on one side of the protrusion 101b. At least two sets of protrusions 101b and springs 101c are provided.
[0032] Furthermore, the conical screen 101 is set in a conical funnel at a certain angle to ensure that large particles can slide to the center.
[0033] Specifically, a circular plate 102 is provided at the bottom of the conical screen 101, a crushing blade 103 is provided on one side of the circular plate 102, and a first motor 104 is provided on the other side of the circular plate 102. The first motor 104 is installed in the mounting housing.
[0034] Furthermore, the circular plate 102 is horizontally positioned to facilitate the crushing of large sludge particles by the crushing blade 103. When the first motor 104 drives the crushing blade 103 to rotate, the conical screen 101 and the circular plate 102 will rotate irregularly. The spring 101c exerts a reaction force on this, thereby causing the conical screen 101 and the circular plate 102 to reciprocate irregularly, effectively preventing clogging of the filter holes and further enhancing the filtration efficiency.
[0035] Specifically, a support cylinder 105 is provided on the outer side of the conical screen 101. The support cylinder 105 has a first annular groove 106 and a second annular groove 107 inside, with several second annular grooves 107. A sliding column 105a is provided at the bottom of the support cylinder 105, with several sliding columns 105a arranged in a circumferential array. A screening cylinder 108 is rotatably mounted inside the support cylinder 105. The screening cylinder 108 includes an outer cylinder 108a and an inner cylinder 108b, which are fixedly connected by a connecting frame 108c. The outer cylinder 108a includes an annular block 108a1 disposed on its outer side, with several sets of annular blocks 108a1. The bottom circumferential array of the outer cylinder 108a has several sets of first limiting grooves 108a2, and the bottom circumferential array of the inner cylinder 108b has several sets of second limiting grooves 108b1. The first limiting grooves 108a2 and second limiting grooves 108b1 are correspondingly arranged. A support plate 109 is disposed at the bottom of the screening cylinder 108, and a first limiting block 109a and a second limiting block 109b are disposed at the top of the support plate 109. Both the first limiting block 109a and the second limiting block 109b are arranged in a circumferential array and are respectively corresponding to the first limiting grooves 108a2 and the second limiting grooves 108b1.
[0036] Furthermore, the filtered sludge enters the outer cylinder 108a and the inner cylinder 108b respectively. The second motor 109c is started, so the support disk 109 begins to rotate. Since the first limiting block 109a and the second limiting block 109b are located inside the first limiting groove 108a2 and the second limiting groove 108b1 at this time, the rotation of the support disk 109 drives the screening cylinder 108 to rotate. At this time, the water is fully thrown out and flows into the receiving tank 111.
[0037] The outer cylinder 108a is connected to several annular blocks 108a1, which in turn connect to the second annular groove 107. This allows the outer cylinder 108a to rotate freely inside the support cylinder 105, which in turn provides support. A second motor 109c is located at the bottom of the support plate 109, and a fixed plate 109d is located at the bottom of the second motor 109c. The top of the fixed plate 109d is fixedly connected to the sliding column 105a. A cylinder 110 is located at the bottom of the fixed plate 109d, and a base is located at the bottom of the cylinder 110. A receiving groove 111 is formed on one side of the base.
[0038] Furthermore, the cylinder 110 is activated, causing the fixed plate 109d to move downwards. This causes the first limiting block 109a and the second limiting block 109b to gradually disengage from the first limiting groove 108a2 and the second limiting groove 108b1. Ultimately, the support plate 109 disengages from the outer cylinder 108a and the inner cylinder 108b, and the sludge falls onto the support plate 109, facilitating further processing. Example 2
[0039] Reference Figures 1-8 This is the second embodiment of the present invention, which provides a sludge treatment device for environmental engineering. Through a screening component, a rotating screening cylinder is used to remove water using centrifugal force. Its unique design, consisting of an outer cylinder 108a and an inner cylinder 108b, further enhances the efficiency of sludge-water separation and prevents excessive sludge thickness from affecting efficiency. A specially shaped conical screen 101 guides large sludge particles to the center, where they are crushed by a crushing blade 103. Since the conical screen 101 is only rotatably connected to the first annular groove 106 via a support plate 101a, the irregular, regular tension spring 101c causes the conical screen 101 to reciprocate in short strokes under the action of the crushing blade 103 and the motor, preventing clogging of the filter holes and further enhancing filtration efficiency.
[0040] When using this device, the sludge mixture is first placed into the conical screen 101, and the first motor 104 is started to drive the crusher 103 to rotate. When the first motor 104 drives the crusher 103 to rotate, the conical screen 101 and the circular plate 102 will rotate irregularly. The spring 101c will exert a reaction force on it, thereby causing the conical screen 101 and the circular plate 102 to reciprocate irregularly, which effectively prevents the filter holes from clogging and further enhances the filtration efficiency.
[0041] After filtration, the sludge enters the outer cylinder 108a and the inner cylinder 108b respectively. The second motor 109c is started, so the support plate 109 starts to rotate. Since the first limiting block 109a and the second limiting block 109b are located inside the first limiting groove 108a2 and the second limiting groove 108b1 at this time, the rotation of the support plate 109 drives the screening cylinder 108 to rotate. At this time, the water is fully thrown out and flows into the receiving tank 111.
[0042] When the dewatered sludge needs to be discharged, cylinder 110 is activated, causing the fixed plate 109d to move downwards. This causes the first limiting block 109a and the second limiting block 109b to gradually disengage from the first limiting groove 108a2 and the second limiting groove 108b1. Finally, the support plate 109 disengages from the outer cylinder 108a and the inner cylinder 108b, and the sludge falls onto the support plate 109 for further processing.
